Since the creation of CERN in 1954 until mid 1980s, the audiovisual service has recorded hundreds of hours of moments of life at CERN on audio tapes. These moments range from inaugurations of new facilities to VIP speeches and general interest cultural seminars. The original support of these recordings are open-reel tapes which are known to have a limited life time and some recordings were already damaged when the preservation process started in June 2005. This explains the heterogeneity of the quality of the recordings you will find in this catalogue. The digitisation is foreseen to be completed end of 2006. The digital recordings are provided in ogg vorbis open audio format (find out how to replay OGG files).
